MACHINE FOR SPONGI NG AND SHRINKING CLOTH.

SPECIFICATION forming part of Letters Patent No; 511,216, dated December 19, 1893.

, application filed August 30, 1893. Serial No. 484,368. (No model.)

ofRochester, in the county of Monroe and State of New Yorlqhave invented a new and useful Improvement in Machines for Sponging'and Shrinking Cloth, which improvement is fully setforth'in the following specification and shownin the accompanying drawings.

My invention relates to machines for dampening and shrinking cloth in the roll by using steam, and themain object of the inventionis to supply dry steam to the cloth so that the latter shall be evenly and uniformly dampened and not oversaturated in spots. To accomplish thisresult I employ a horizontal perforated 'metaldrurn and introduce into it in bulk through one end live steam through an axial perforated pipe extending nearly the whole length of the interior of the drum. This steamintroduced into the drum, under pressure, passesout through the perforations in the drum and enters the cloth wound thereon. iTo'render this steam dry,l introduce into the drum at the opposite end through an imperforate pipe another current of steam; the pipe being bent in spirals or otherwise to occupy a considerable portion of the space Within the drum. This steam pipe impartsja'dditionalheat to the bulk or free, steam filling the drum which serves to vaporize any particles or small masses of water that may chanceto be introduced into or form withinthedrum from the free steamcontained therein. This additional heating of the free steam within the drum insures anoutward flow of dry steam from the druminto the cloth.

The inventionis hereinafter more fully departs being brokeuaway. Fig. 2 shows the steam drum,-with the interior parts, the drum and the steam supply pipe being centrally and longitudinally sectioned, parts being broken away. Fig. 3 shows the holder for the drying pipe the latter being transversely sectioned as on the dotted line3 3 inFigpl, and

viewed as indicated by the arrow pointed thereon. Fig. 4 is a transverse section through the inlet head for the drying steam,

taken on the, dotted line 4 4 in Fig. 5, and

Viewed as indicated by the arrow pointed thereon. Fig. 5 is a side elevation of the inlet head. Fig. 6 shows the relative position of the steam drum and other parts of the ma chine. Figs. 2 and 6 are drawn to scales smaller, and Figs. 4 and 5 to a scale larger, than that of Figs. l and In this invention a horizontal perforated metal steam drum or cylinder A, is provided having heads,B O,secured thereto with holding screws 0., simple packing rings Z) being insorted between the heads and the adjacent ends of the drum. The heads are formed with cylindrical hubs, 0 cl, which constitute journal bearings for the drum, restingin the frame D. The head C is extended beyond the bearing in the frame to form part of an ordinary stuffing box E, as shown in Fig. 1.

F, Figs. 1 and 2, is asteamsupply pipe for the drum leading from some convenient steam generator. This pipe includes a common T connection e, and is provided with a valve G of common construction to control the passage through it. The pipe F passes through the stuffing box E and the head 0, and extends nearly the whole length of the drum, as shown in Fig. 2, the axes of the drum and pipe being common. This pipe is perforated within the drum and formed with anopen inner end, so that the i'nflowing steam may escape evenly into t11e' druni as indicated by arrows; thence the steam flows outward through the perforations in the sides of the drum to enter the cloth wound thereon.

His a steam heating pipe, leading into the drumthrough the head B. This pipe includes a T coupling f, and is provided with a valve I of common construction and leads from a steam generator the same, or other than, the one from which pipeF leads. The pipe His formed with an enlarged part L constituting an inlet head for the in flowing steam. This head is hollow and cylindrical, and it is formed with one or more peripheral openings, g, Figs. t and 5, through which the steam enters. This inlet head is central within the T coup- .lingf, as shown in Fig. 1, and stuffing boxes h h, are threaded into the opposite ends of the T coupling their inner ends being in easy contact with the inlet head. Glands z 11 of common kind are threaded into the stutfing boxes h h. The pipe H passes through the right-hand stuffing box in the T coupling f, and is threaded into the end of the hub B, opening into the space z therein. Ajam nut is, is provided to hold the pipe firmly in the.

head. A stem Z, preferably solid, extends from the inlet head outward through the lefthand stufling box and is squared at m to receive a crank, 71-, Fig. 6.

A metal diaphragm 19, Figs. 1, 2 and 3, is secured to the inner face of the head B by simple fastening screws 0, in position to cover the space ,2 in said head. A packing ring 0* is usually employed to render the joint between 13 and B steam tight. Into the diaphragm, I insert horizontally the end of a spiral pipe K, as shown, communicating with the space 2', and consequently with the interiorof the pipe H. The manner of securing this pipe to the diaphragm or holder 19 is not essential care being taken to have the parts rigid and steam tight. I usually thread the parts together, as shown, and employ a jam fnut s, 'to more firmly unite the parts. The

pipe K is imperforate and extends the entire length of the interior of the drum, and bends at t to return within the coil to a point a near the diaphragm where it again bends and passes longitudinally through the horizontal portion of the pipe F, and out through a stuffing'boxP inserted in the T coupling e, thence into the open air, terminating at 4;. will be understood that thepipes H and-K (together with the space 2) form a continuous passage into, through and out of the drum A and that steam entering the pipe Hwill traverse the entire length of the pipe K and out through the opposite head (0) of the drum without communicating with the free steam filling the body of the drum. Thus there are two independent currents of steam flowing 'into and through the drum in opposite'directions, one escaping through the perforations in the sides of the drum, and the other along'a passage through the opposite head of the drum into the open air beyond. On

account of the form given the steam-drying pipe K there is great length of it within the drum, it filling a considerable part of the space within the latter, andall of the bulk steam at any time within the drum is. either in contact with or near to the pipe and is rendered dry from the heat given 0E from said pipe. A valve 0 of common construction is added to the pipe K, near its terminus, to control the passage through it. The inner end of the pipe F, Fig. 2, is formed with an open head through which the pipe K passes, space being left around the pipe K out through which steam may flow to the extreme end of the drum. Now it will be observed that when Now it the drum is turned to wind the cloth on or oit, the horizontal portion of the pipe H and the entire pipe K turn with it, while the supply pipe F is stationary. The part of the pipe K from the elbow to to the ends sweeps around in a circlewhen the drum IS turned and at each time the extreme end Ii P0111128 downward any condensed Water or drip that the pipe may contain escapes into a suitable receptable placed beneath it, and the flowing of steam from pipe H through K tends to carry any condensed water that may form in the latter pipe out at the discharge end '0.

The perforated drum A is mounted transversely upon a frame D, Fig. 6, 1n the usual manner, a delivery roll y for the cloth and a receiving roll a", being also mounted .on the frame, each being provided with a crank, as shown, to operate it, said rolls w and y coacting with the drum in treatingthe cloth as stated.

WVhat I claim as my invention 1s 1.
